That is the amount that provides not too much nor too little resistance. So, you can throw punches with good power. Also, its swinging imitates well the moving of a real opponent so that you can practice the defense and offense movements.

If the bag is too light, it swings away too much. It does not provide enough resistance to placing a power punch on it.

If it is too heavy, you will have a feeling as if you were hitting a wall. The swinging is minimal. Hence it will not force you to move it around.

To sum up, a good equipment develops your punching and moving skills. That is why it is crucial to pick the right heavy bag weight for you.

Some words about getting a lighter bag

In some case getting a bag that much lighter than your weight is not a wrong choice.

For example, when you want to use it for cardio training. When you do such a workout, there is no need to hit it with massive power; just light punches are thrown. Hence, you do not need equipment that provides high resistance.

Also, when you hit a lighter bag, it swings more, and that is an excellent opportunity to practice defense and offense skills. You need to move away to be not being hit by the returning bag. But, you also need to step here and there to place the next punches on it.

For example, Mike Tyson used this technique.

To sum up

The best is to get a bag that is half of your weight. That will be suitable for any types of workout.
